Recommendation for a Programmer for a 2003 GMC Yukon XL 2500 with 8.1 Liter V8 Gas Engine

I can promise you that I will only lead you to the right parts for your vehicle every time. For your 2003 GMC Yukon XL with the 8.1 liter gas engine, there are 2 options for Edge programmers. First is the Color Screen Evolution, # EP85150, that you have referenced. The other option is the Color Touch Screen Evolution, # EP85250.

The difference between these two parts is that the former has a color screen and push button interface while the latter has a touch screen interface. Otherwise, both offer the same features, including the ability to enter your tire size so that it can make the necessary adjustments so you know you are going the correct speed.

There are several settings you can choose from including economy, towing, and performance, that I am certain you will find the right balance of power and fuel economy. I have included a link to the installation instruction manual for you to view.

For a dash pod, again there are 2 options. If you go with the color screen model with push button interface, # EP85150, then all you will need for a dash pod is # EP28300. If you decide to go with the touch screen model, you will need the same pod and an adapter, # EP98003.

Other parts that will offer more power/fuel economy are air intake and exhaust upgrades. For air intake, I recommend the dry filter AFE system, # AFE51-10091. Dry filters are good for paved and semi-dusty roads.

Exhaust upgrades will also provide more power and better fuel economy. For your vehicle, we have the MagnaFlow System, # MF15716. I have a MagnaFlow system on my GXP and have seen an increase of 4 percent in miles per gallon. It does not seem like much but I have only had the system for a few weeks.
